Which option should be selected to create a new central model from an existing workshared project?

To create a new central model from an existing workshared project, the option to select is Detach from Central. This functionality allows you to make a copy of the existing central model without any links to it, resulting in a standalone file that can later be designated as a new central model.

When you detach from the central model, you're essentially breaking the connection with the original model while retaining its current state, thus allowing you to work independently. This process is crucial especially when you want to either reset your work for a new phase of a project or maintain a certain version while developing further.

In contrast, the other options serve different purposes. For example, auditing a file is a method to check and repair a model before use, which doesn't affect the creation of a new central model. Relinquishing all mine is about freeing up resources and permissions granted to your user, whereas collaborating in the cloud refers to sharing and managing a project in a cloud environment, which does not directly create a new model from the existing one.
